The Edelbrock Signature Valve Covers are available for most popular applications in two show stopping finishes; brilliant triple chrome plated with a stamped logo or a modern stealthy textured black with a screen printed logo. Low profile covers are stock height and tall profile are about 1-1/2" taller than stock. Tall valve covers will clear most aluminum rockers with moderate lift cams but will not clear stud girdles. Most include OE-style breather baffles, except where noted - (no baffle), to prevent excessive oil usage through the pcv valve. They feature provisions for all emissions equipment, with rubber grommets for the pcv and breather holes included.
